I can log in with Squirrelmail from anywhere and I can send mail from Squirrelmail to anywhere.
I can ONLY receive mail from within, that is, testATkateslabDOTcom & katiijATkateslabDOTcom can send and receive to each other without problems. I can also telnet into the server and successfully send mail using an outside "from" address.
Any mail sent from the outside world will not arrive, and I am not familiar enough with mail logs to be able to identify the problem.

Code:

I have checked my dns against many online tools and it checks out OK.
From reading related posts, I believe the following files hold pertinent information:
Tail of maillog right after I send an email from my gmail account (it is similiar no matter the sender)
